/**
 * #GDBusServer is a helper for listening to and accepting D-Bus
 * connections. This can be used to create a new D-Bus server, allowing two
 * peers to use the D-Bus protocol for their own specialized communication.
 * A server instance provided in this way will not perform message routing or
 * implement the org.freedesktop.DBus interface.
 * 
 * To just export an object on a well-known name on a message bus, such as the
 * session or system bus, you should instead use g_bus_own_name().
 * 
 * An example of peer-to-peer communication with G-DBus can be found
 * in [gdbus-example-peer.c](https://git.gnome.org/browse/glib/tree/gio/tests/gdbus-example-peer.c).
 *
 * Since: 2.26
